(Choose 1 answer)
The amount of water in a one-liter bottle is approximately normally distributed with a mean of 1.05 liters with a standard deviation of 0.015 liter. If a sample of 5 bottles is selected, find the probability that the sample mean amount contained is less than 1.03 liters.
Let P(Z < -0.02) = 0.4920; P(Z < 0.02) = 0.5080; P(Z < 2.98) = 0.9986;P(Z -2.98)=0.0014)
A. 0.0014
B. 0.4920
C. 0.9986
